Redundant buffering costs memory, cache foot print and time. In the
worst case, you end up with an output and an input buffer between each
set of transformations. That can result in a measurable overhead for
cases that are not IO bound.

This is exactly why I was pointing into the libarchive direction.
Thinking properly about minimizing resource usage here is hard work.
